Question

我正在尝试的是获取当前位置（坐标），我想在网站上发布这些坐标。我用WAMP制作了一台服务器。我在java中编写了PHP代码和代码。没有错误，但网站上没有公布数据

PHP代码

<?php
echo 'Hello, world!';
$json = $_GET['jsonpost'];//get the post you sent...
$data = json_decode($json); //decode the json formatted string...
print_r($data);
$id = $data->id;
$devid = $data->devid;
$latitude = $data->latitude;
$longitude = $data->longitude;
$service = $data->service;
$con = mysql_connect("","","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("a5234826_ul", $con);
$devid = $_POST['devid']; 
$latitude = $_POST['latitude'];
$longitude = $_POST['longitude'];
echo "devid" +$devid;
echo "latitude" + $latitude;
echo "longitude" + $longitude; 
$sql = "INSERT INTO  `a5234826_ul`.`locations` (
`id` ,
`devid` ,
`latitude` ,
`longitude` ,
`service`
)
VALUES (
NULL ,  '$devid',  '$latitude',  '$longitude', '$service'  
)";
if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
mysql_close($con);
echo json_encode($variable);
?>

Answer 1

正如第一次猜测，第3行不应该是：

$json = $_POST['jsonpost'];//get the post you sent...

Answer 2

如果您将第3行更改为：

$json = $_REQUEST['jsonpost'];

您将通过HTTP支持POST和GET方法。如果您在开发环境中工作以确保请求在没有HTTP请求细节的情况下发送到您的服务器，这将非常有用。

$ _ REQUEST应谨慎使用，因为变量将包含$ _COOKIES，$ _GET和$ _POST的内容。

您应该在脚本中访问数据后始终清理数据

Answer 3

他们与服务器的连接是什么？

您是否检查了/ etc / httpd / logs / ..或者您的发行版记录http流量的位置？我会先这样做，以确定实际上是从设备发送流量。

如果成功，数据库是否已填充？你也可以简单地添加语句来跟踪php代码到一个文件（例如/ tmp）和尾部，以查看错误是否存在于代码中，或者只是遵循代码执行模式，即使是在这个简单的情况下。

你正在做骰子（'无法连接：'。mysql_error（））;和print_r，以及写你好世界，你在哪里看到这个！？正如我所提到的，将其写入/ tmp文件进行分析。

我正在努力假设您的服务正常运行。 logcat说什么？他们的任何可辨别的输出是否表明存在问题？

php端的代码本身看起来有些匆匆写了，这里不太关键但是这里的一些规则可能会在将来为你节省很多问题。 echo json_encode是什么（$ variable）;在你的代码末尾做什么？

来自android的数据不在php上发布
